srarns PATENT `If f 'Gnarls-CLEANER.

Herculaneum, State of Missouri, havefin-` vented certain new and usefulImprovements in Grate-Cleaners, of whichthe following is aspecification, containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.i

The object of my invention is to design a means of removing clinkers,dross, slag or other materials from moving grates of the to prevent theclog-` sectional chain variety; ging of the grate yopenings so as topermit air to pass'freely through the grate.

My invention nds particular application in smeltingoperations'especially the reduction and purification of lead. ,In theconventional machine now used in the lead industry, a man must bestationed at `a suitable point in the path of the chain grate; yby meansof pokers kept open so that sufficient air is permitted to pass throughto' bring about the necessary oxidation required by the process. Myinvention will entirely supplant this operator, will absolutely keep thegrate in an operatat a Very low initial cost and at a nominal upkeepcharge.

W ith the above and other objects in View, my invention has relation tocertain novel features of construction and operation, examples of whichare described in the following specification and illustrated in theaccompanying drawings in which* Figure 1k is a fragmental longitudinalsectional elevation of my device. Fig. 2 is a cross-section on the line2 2 of Fig. 1. Fig. 3 is an enlarged detail plan of a grate section.

In the drawings numerals l and 5 designate two stands secured at thesides of the grate section G.

7 designates a horizontal cross beam connecting the stands 4 and 5 attheir upper extremities.

8 designates a cylinder firmly secured to the shaft 9 which is journaledto 4 and 5 at 10 and 1l.

12 and 13 represent two guides secured firmly to each grate section.

1st and 15 designate two feet extending from the guides 12 and 13; thesefeet are supported on tracks (not shown), hence each grate section canbe moved on its base on the Specification of Letters Patent.

track around its endless path (not shown) .in drawing.

'lhe lateral surface covered with forming to the 6, so that when 4finlike projections 8', conopenings in the grate section the cylinder `8and the grate section 6 are in the proper relative position, theprojections on the cylinder will engage the grate openings. Asthe gratesectirns aremoved in their path, the cylinder 8 by frictional contact orotherwise` contact ,is shown) is caused .to Y revolve thereby causingthe projections on the cylin .deryto stamp or press out the foreign sub-`stancethat may be lodged in the grate holes.

My preferred'form of bone, but the cylinder* can be designed for Aanygrate by changing the lshape and posirtioning 'of the projectionS .oncylinder S. At certain times, it becomes desirable to adjust 'thespacing :between the cylinder and the grate and sometimes for repairs toraise the cylinder 8 entirely away from the grate; this is accomplishedin a very simple manner as follows The stands 4i and 5 have verticalslots (not shown) cut in them, the widths of which slightly exceed thediameter of the shaft 9 so that by raising or lowering the shaft in thisslot the desired object is attained. To facilitate the moving of theshaft in the slots the arms 16 and 17 are vided; at their lower endsthey are fastened to the shaft 9 and at their upper to a horizontalmovable member which lies ina slot (not shown) in the upper portion ofbeam 7. To the center of this horizontal member is secured aneye 18; tothe beam 7 is secured the eye 19. 'lhe lever 20 by means of a pin 2l isfulcrumed at eye 19 and by means of pin 22 is rotatively secured to thehorizontal movable member. It will be readily seen that by moving thelever 20 the cylinder 9 will be moved in a vertical plane in and out ofengagement with the grate. Tosecure the correct lateral positioning ofthe cylinder 8, springs 23 and 24 are positioned as shown.

What I claim and mean to secure by Letters Patent is- 1. In a device ofthe character described, a grate, a cylinder having projections,adjustable means, to vary the space between the grate and the cylinderand for bringing the projections of said cylinder into selectiveengagement with the openings in said grate.
